[0006] Technical problem to be solved by the invention

[0007] However, the screwless terminal described in Patent Document 1 requires the operator to use both hands when plugging and unplugging the wire. Specifically, when plugging and unplugging the wire, the operator holds the screwdriver with one hand and the wire with the other hand. Then, the operator presses the release button with the screwdriver and keeps the button pressed while plugging and unplugging the wire. Then, the release button is released to complete the operation. Thus, in the screwless terminal described in Patent Document 1, the operator needs to use both hands at the same time to plug and unplug the wire, which makes the operation difficult and cumbersome.

[0090] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0091] <Application Examples>

[0092] The terminal block described in the present application is, for example, a terminal block that can be used to detach various wires such as power lines and signal lines in electrical equipment such as distribution boards, operating machinery, and PV equipment. As specific structures of the wires, various cables such as single wires and twisted wires with their outer skins stripped off, and various wires such as ferrule terminals can be exemplified. Below, with reference to the accompanying drawings, the terminal block 1 illustrated in the drawings will be described.

[0093] <First embodiment>

[0094] Figure 1 It is a perspective schematic diagram showing an example of the appearance of the terminal block 1 according to the present application. Figure 2 1 is a top view schematically showing an example of the appearance of the terminal block 1 described in the present application. The terminal block 1 described in the present application is formed in a substantially rectangular parallelepiped shape. It should be noted that in the following description, the direction of the terminal block 1 is Figure 1, the left front side is indicated as front (front), the right deep side is indicated as rear, the left deep side is indicated as left, the right front side is indicated as right, the top is indicated as top, and the bottom is indicated as bottom. These are directions for convenience of explanation and are not used to limit the direction when the terminal block 1 is used. Although a ferrule terminal is used as an example for explanation as the wire 2 inserted into the terminal block 1, in addition to the ferrule terminal, various cables such as single wires and stranded wires with the outer skin stripped can also be used as the wire 2.

[0095] The terminal block 1 described in the present application has a housing 10 formed in a substantially rectangular parallelepiped shape. On the upper surface of the housing 10, four circular openings 100 are provided at four locations for inserting the wires 2. Rotating members 11 are installed around the openings 100 so that a portion of the wires 2 can be inserted into the openings 100. It should be noted that Figure 2 In the figure, a part of the rotating member 11 is removed so that the opening 100 of the housing 10 can be clearly seen. The rotating member 11 is a member operated by an operator when inserting the wire 2 into the terminal block 1. When the operator rotates the rotating member 11, the rotating member 11 rotates along the opening 100, thereby adjusting the spring member 12 (see FIG. 1 ) described later in the housing 10. Figure 3 The wire 2 can be inserted and removed by the action of the terminal block 13 (such as the above) and the terminal portion 130 of the terminal member 13 formed of a conductive material protrudes from the lower surface of the housing 10. The wire 2 inserted into the terminal block 1 is electrically connected to the terminal member 13 inside the housing 10, and becomes conductive with the terminal portion 130.

[0096] Figure 3 It is a perspective exploded schematic diagram showing an example of the terminal block 1 according to the present application. Figure 3 The terminal block 1 is decomposed and represented. The terminal block 1 is formed by connecting a plurality of structural units 1a each having a spring component 12 and a rotating component 11. Various components such as a part of the housing 10, a rotating component 11, a spring component 12, and a terminal component 13 are housed in one structural unit 1a. The structural unit 1a can connect the opening 100 on the upper surface of the housing 10 to the front and back in different positions from left to right. The end surface cover 101 that becomes the front surface and the back surface of the housing 10 is connected to the front and rear ends of the connected plurality of structural units 1a. In addition, the connected plurality of structural units 1a can be separated. Therefore, by connecting an appropriate number of structural units 1a corresponding to the use and purpose, and connecting the end surface cover 101 to the front and back, a terminal block 1 with an appropriate number of openings 100 can be formed. It should be noted that the end surface cover 101 can also be connected to the front and back of one structural unit 1a.

[0097] Figure 4 This is a front schematic diagram showing an example of the internal structure of the terminal block 1 according to the present application. Figure 5This is a schematic perspective view showing an example of various components housed in the housing 10 of the terminal block 1 described in the present application. Figure 4 This is a front schematic diagram showing various components of the frontmost structural unit 1 a in a state where the end surface cover 101 on the front surface side of the housing 10 is separated from the terminal block 1 so that the interior can be clearly seen. Figure 5 The terminal block 1 is shown as a schematic perspective view in which the rotating member 11 , the spring member 12 , and the terminal member 13 housed in the housing 10 are removed so that their relationship can be clearly seen.

[0098] The rotating member 11 is formed as a whole in a generally cylindrical shape with the central axis in the vertical direction, and the center of the hollow is an insertion passage through which the wire 2 can be inserted. The upper end of the rotating member 11 is exposed upward from the upper surface of the housing 10 and is formed by the operation of the operator. The lower end of the rotating member 11 is configured to press the spring member 12 from above. The spring member 12 is a flexible leaf spring fixed to the terminal member 13. The terminal block 1 sandwiches the wire 2 between the spring member 12 and the terminal member 13, and the spring member 12 presses the wire 2 toward the terminal member 13, thereby being able to hold the wire 2. The flexible spring member 12 is acted upon by the rotating member 11, and moves between a holding position for holding the wire 2 and a release position for releasing the wire 2 from the holding.

[0099] Figure 6 and Figure 7 It is a schematic perspective view showing an example of the rotating member 11 included in the terminal block 1 according to the present application. Figure 6 It is shown from an oblique upward perspective. Figure 7 It is shown from an oblique downward angle. Figures 4 to 7 , the rotating part 11 is described. The rotating part 11 has a rotating cylindrical part 110 (cylinder part), an operating part 111, a driving cam part 112 and other parts. The rotating cylindrical part 110 is formed in a substantially cylindrical shape so that the wire 2 can be inserted therethrough. The upper end of the rotating cylindrical part 110 is exposed to the upper surface side of the housing 10, and the exposed part becomes an extension part 110a extending around the opening 100 into which the rotating part 11 is inserted. A notch 110b is formed in a part of the extension part 110a, as described later, so that the display part 102 (see Fig.13The operating portion 111 is formed to extend laterally from the protruding portion 110a on the upper end side of the rotating cylindrical portion 110, and is used as an operating lever to receive an operation for rotating the receiving rotating member 11 around the central axis of the rotating cylindrical portion 110. The driving cam portion 112 is an end face cam formed on the lower end side of the rotating cylindrical portion 110, and acts on the spring member 12 to cause the spring member 12 to operate. The driving cam portion 112 protrudes downward along the circumference at the front end side of the axial direction of the rotating cylindrical portion 110, and has a circumferentially inclined portion 112a, and a non-inclined flat portion 112b. The inclined portion 112a is formed obliquely and the flat portion 112b is formed parallel to a virtual plane of the rotating member 11 that is orthogonal to the axial direction of the rotating cylindrical portion 110.

[0100] Figure 8 It is a perspective schematic diagram showing an example of the spring member 12 and the terminal member 13 included in the terminal block 1 according to the present application. Figure 8 The image is shown from an oblique upward perspective. Figure 4 , Figure 5 and Figure 8 , the spring member 12 and the terminal member 13 are described. The spring member 12 is formed by bending a flexible material such as a metal thin plate into a substantially V-shape. The spring member 12 formed into a substantially V-shape has a bent portion 120, one piece extending from the bent portion 120 is a fixed piece 121 fixed to the terminal member 13, and the other piece extending from the bent portion 120 is a pressing piece 122 used as a leaf spring to press the inserted wire 2.

[0101] The terminal member 13 is formed in a shape that fits inside the housing 10, and has a terminal portion 130 that serves as a terminal that conducts with the inserted wire 2, a fixed wall 131 to which the fixing piece 121 of the spring member 12 is fixed, a conducting wall 132 that conducts by sandwiching and holding the inserted wire 2 between the fixed wall 131 and the pressing piece 122, and a connecting wall 133 that connects the fixed wall 131 and the conducting wall 132. The terminal portion 130 is formed by extending the lower end of the conducting wall 132 to the outside of the housing 10. The conducting wall 132 and the terminal portion 130 serve as a bus bar that conducts between the wire 2 held in contact with the conducting wall 132 and other circuits connected to the terminal portion 130. The fixing piece 121 of the spring member 12 is fixed to the fixing wall 131 of the terminal member 13 with the folding portion 120 facing upward, and the pressing piece 122 bent with the folding portion 120 as a fulcrum is used as a leaf spring. The pressing piece 122 extends from the folding portion 120 to the conducting wall 132 in an obliquely downward direction, and the front end portion abuts against the conducting wall 132. In addition, the pressing piece 122 abuts against the driving cam portion 112 of the rotating member 11 from below, and applies force to the rotating member 11 upward. A resin guard 123 is installed on the upper surface of the pressing piece 122 at the portion abutting against the driving cam portion 112 of the rotating member 11. The guard 123 abuts against the driving cam portion 112 of the rotating member 11 that rotates as a driving node, and the pressing piece 122 of the spring member 12 that abuts against the driving cam portion 112 as a driven node and presses downward, and has the function of preventing damage such as scratches and twists caused by friction.

[0102] The operation of the terminal block 1 formed as described above will be described. Figures 9 to 11 1 is a front schematic diagram showing an example of the terminal block 1 according to the present application. Figures 9 to 11 Various components of the frontmost structural unit 1 a are illustrated in a state where the end surface cover 101 on the front surface of the housing 10 is separated from the terminal block 1 and the interior is visible. Fig. 9 It shows the state where no wire 2 is inserted. Fig.10 Indicates the state of the insertion of the wire 2 or the release of the inserted wire 2. Fig.11 The state in which the wire material 2 such as the ferrule terminal etc. which has been inserted is held is shown.

[0103] exist Fig. 9 In the illustrated state, the rotating member 11 abuts against the spring member 12 at a portion of the driving cam portion 112 that protrudes slightly downward. Fig. 9 In the illustrated state, the front end side of the pressing piece 122 of the spring member 12 is located at the upper holding position. Fig. 9In the illustrated state, when the wire 2 is not inserted, the pressing piece 122 of the spring member 12 is located at the front end abutting against the conducting wall 132 or near the conducting wall 132, and the upper surface abuts against the driving cam portion 112 from below via the guard 123. Therefore, the hollow at the center of the rotating member 11, which becomes the insertion passage through which the wire 2 is inserted, becomes a state where its front end is blocked by the pressing piece 122.

[0104] Fig.10 Indicates the operator’s Fig. 9 The illustrated state is a state in which the operating portion 111 of the rotating member 11 is operated and the rotating member 11 is rotated clockwise (clockwise) about 30 degrees around the central axis of the rotating cylindrical portion 110. Fig.10 In the illustrated state, the front end of the downwardly protruding portion of the driving cam portion 112 of the rotating member 11 abuts against the spring member 12. The pressing piece 122 of the spring member 12 is pressed downward by the front end of the driving cam portion 112, so that it is bent downward with the bending portion 120 as a fulcrum and is located at the lower release position. Fig.10 In the illustrated state, when the wire 2 is inserted, the wire 2 is released from the pressing of the pressing piece 122 of the spring member 12, so the wire 2 is easily pulled out. Fig.10 In the illustrated state, when the wire 2 is not inserted, the wire 2 can be easily inserted because the insertion path through which the wire 2 is inserted is open. Fig.10 In the illustrated state, since the spring member 12 contacts the flat portion 112b of the driving cam portion 112 via the guard 123, it is more stable than the state of contacting the inclined portion 112a, and friction is generated between the rotating member 11 and the housing 10. Therefore, even if the operator does not apply force to the operating portion 111, the terminal block 1 maintains Fig.10 The instantiation state will not be restored to Fig. 9 Therefore, for example, after operating the operation unit 111 with the right hand, the operator can insert or remove the wire 2 with the right hand, and can easily perform a one-hand operation of operating the operation unit 111 with the right hand again.

[0105] Fig.11 Indicates that the operator Fig.10 The illustrated state is a state where the wire 2 is inserted into the terminal block 1, the operating portion 111 of the rotating member 11 is operated, and the rotating member 11 is rotated counterclockwise (rotated counterclockwise) about 30 degrees around the central axis of the rotating cylinder 110. Fig.11In the illustrated state, the pressing piece 122 of the spring member 12 located at the holding position presses the inserted wire 2 toward the conducting wall 132 of the terminal member 13. By clamping the wire 2 between the pressing piece 122 of the spring member 12 and the conducting wall 132 of the terminal member 13, the wire 2 is held in contact with the conducting wall 132 in the housing 10, and is in a state where it can be conducted with the terminal portion 130.

[0106] Fig.12 and Fig.13 This is a schematic plan view illustrating an enlarged example of a part of the terminal block 1 described in the present application. Fig.12 Indicates the state that the inserted wire 2 can be maintained, corresponding to Fig. 9 and Fig.11 . Fig.13 Indicates the state of release, corresponding to Fig.10 . Through the operator Fig.12 In the state shown in FIG. 1 , the operation portion 111 of the rotating member 11 is turned rightward by about 30 degrees. Fig.13 The upper surface of the housing 10 is provided with a display portion 102 indicating that the spring member 12 is in the released position, and the letter "Rel" indicating the released position is engraved near the display portion 102. The display portion 102 is formed to be conspicuous by, for example, coloring it with a color different from the surroundings, or by emitting light from a light-emitting element such as an LED. Fig.13 In the released state shown in the example, the display unit 102 is exposed from the cutout 110b of the extension 110a formed at the upper end of the rotating cylindrical portion 110 of the rotating member 11. Thus, the operator can see that the spring member 12 is in the released position in conjunction with the nearby "Rel" indication. Fig.12 In the illustrated state, since the display portion 102 is blocked by the extending portion 110 a , the operator can clearly see that the spring member 12 is in the holding position.

[0107] As described above, the terminal block 1 of the first embodiment can be easily operated with one hand. In addition, the terminal block 1 of the first embodiment can easily confirm that the spring member 12 is in the release position or the holding position.

[0108] The terminal block 1 of the first embodiment of the present application is not limited to the above-mentioned method, and can be developed into various methods. For example, in the terminal block 1 of the first embodiment, the protective member 123 is not necessarily required, and it can also be configured so that the spring member 12 and the rotating member 11 are directly in contact. In addition, for example, in the terminal block 1 of the first embodiment, the rotating cylindrical portion 110 of the rotating member 11 is not necessarily formed into a roughly cylindrical shape, but can also be a cylindrical shape that can be inserted with the wire 2. Specifically, instead of the rotating cylindrical portion 110, a cylindrical portion formed into a roughly cylindrical shape by various bottom surface shapes such as a roughly elliptical shape, a roughly regular octagonal shape, or other polygonal shapes when viewed from above can be used. In the following, various embodiments in which the terminal block 1 of the first embodiment is further deformed are described.

[0109] <Second embodiment>

[0110] The second embodiment is based on the first embodiment, and various components are added to stabilize the force pressing the spring component 12 downward. In the second embodiment, for the same structure as the first embodiment, the same reference numerals as the first embodiment are used, and the description of the first embodiment is referred to, and the detailed description is omitted. Since the outer shape of the terminal block 1 and the structure connecting the plurality of structural units 1a of the second embodiment are substantially the same as those of the first embodiment, the first embodiment is referred to.

[0111] Fig.14 This is a front schematic diagram showing an example of the internal structure of the terminal block 1 according to the present application. Fig.15 and Fig.16 This is a schematic perspective view showing an example of various components housed in the housing 10 of the terminal block 1 described in the present application. Fig.14 This is a front schematic diagram showing various components of the frontmost structural unit 1 a in a state where the end surface cover 101 on the front surface side of the housing 10 is separated from the terminal block 1 so that the interior can be clearly seen. Fig.15 The terminal block 1 is shown as a schematic three-dimensional view in which the rotating member 11 , the spring member 12 , the terminal member 13 , the pressing member 14 , and the urging member 15 housed in the housing 10 are removed so that their relationship can be clearly seen. Fig.16 Expressed as from Fig.15The illustrated stereoscopic overview diagram is a stereoscopic overview diagram in which the rotating component 11 is further removed so that the relationship between other components can be clearly seen. The terminal block 1 of the second embodiment is further provided with a pressing component 14 and a force applying component 15 relative to the first embodiment. The pressing component 14 is located between the rotating component 11 and the spring component 12, and is configured to be movable up and down. The pressing component 14 is a component that receives pressure from the rotating component 11 to press the spring component 12 downward. The pressing component 14 is formed as a whole into a roughly cylindrical shape with the central axis in the vertical direction, and the center of the hollow becomes an insertion passage through which the wire 2 can be inserted. The force applying component 15 is a component that has a force such as a compression coil spring that applies force to the pressing component 14 upward.

[0112] use Figures 14 to 16 , the spring component 12 and the terminal component 13 are described. In the terminal block 1 of the second embodiment, the spring component 12 and the terminal component 13 are configured in substantially the same manner as the terminal block 1 of the first embodiment. The spring component 12 of the terminal block 1 is formed by bending a flexible material such as a metal thin plate into a substantially V-shape. The spring component 12 formed into a substantially V-shape is bent at a bending portion 120, and has: a fixed piece 121 fixed to the terminal component 13, and a pressing piece 122 used as a leaf spring for pressing the wire 2. The pressing piece 122 of the spring component 12 of the second embodiment is pressed from top to bottom by the pressing component 14 that moves up and down, so no friction is generated in the rotation direction, and thus the guard 123 is not necessarily required. The terminal component 13 of the terminal block 1 is formed with parts such as a terminal portion 130, a driven cam portion 141, a contact portion 142, and an extension portion 143.

[0113] Fig.17 It is a schematic perspective view showing an example of the rotating member 11 included in the terminal block 1 according to the present application. Fig.17 It is shown from a perspective obliquely below. Fig.14 , Fig.15 and Fig.17, the rotating part 11 is described. The rotating part 11 has parts such as a rotating cylinder part 110, an operating part 111, and a driving cam part 112. In the rotating part 11 of the terminal block 1 of the second embodiment, the rotating cylinder part 110 and the operating part 111 are actually the same as those of the first embodiment. The driving cam part 112 of the second embodiment is formed as an end face cam on the lower end side of the rotating cylinder part 110. The driving cam part 112 is formed by protruding two positions at intervals of 180 degrees on the circumference of the lower end side of the rotating cylinder part 110. The driving cam part 112 has parts such as an inclined part 112a and a flat part 112b, which are rotationally symmetrical at intervals of 180 degrees along the circumference. With respect to a virtual plane of the rotating part 11 that is orthogonal to the axial direction of the rotating cylinder part 110, the inclined part 112a is formed obliquely and the flat part 112b is formed roughly parallel. In the driving cam portion 112 , an engaging convex portion 112 c is formed as a protrusion that engages with the pressing member 14 on a flat portion 112 b of a portion that protrudes downward.

[0114] Fig.18 and Fig.19 It is a schematic perspective view showing an example of the pressing member 14 and the urging member 15 included in the terminal block 1 according to the present application. Fig. 20 It is a perspective schematic diagram showing an example of the internal structure of the terminal block 1 according to the present application. Fig.18 The pressing member 14 and the force applying member 15 are shown from an oblique upper perspective. Fig.19 It is shown from an oblique downward angle. Fig. 20 A part of the terminal block 1 is shown in perspective. Figures 14 to 16 ,as well as Figures 18 to 20, the pressing member 14 and the force applying member 15 are described. The pressing member 14 includes a pressing cylindrical portion 140, a driven cam portion 141, a contact portion 142, an extension portion 143 and the like. The pressing cylindrical portion 140 is formed in a substantially cylindrical shape with substantially the same inner diameter and outer diameter as the rotating cylindrical portion 110 of the rotating member 11, and extends downward from the rotating cylindrical portion 110 of the rotating member 11 so as to be arranged with the same central axis. The pressing cylindrical portion 140 of the pressing member 14 is formed so as to be able to pass the wire 2 inserted into the rotating cylindrical portion 110 of the rotating member 11. A notch useful as the driven cam portion 141 is formed in a portion of the circumferential surface that becomes the upper end of the rotating cylindrical portion 110. The driven cam portion 141 is engaged with the driving cam portion 112 of the rotating member 11, and serves as a driven node relative to the driving cam portion 112 of the rotating member 11 serving as a driving node, and a cam mechanism is formed by the driving cam portion 112 and the driven cam portion 141. The driven cam portion 141 serving as a driven node has a high flat portion 141b formed at a position lower than the upper end of the pressing cylindrical portion 140, a driven inclined portion 141a inclined downward from the high flat portion 141b, and a low flat portion 141c located at the lower end of the driven inclined portion 141a. With respect to a virtual plane orthogonal to the axial direction of the pressing cylindrical portion 140 of the pressing member 14, the driven inclined portion 141a is obliquely intersected, and the high flat portion 141b and the low flat portion 141c are formed to be approximately parallel. The driven inclined portion 141a, the high flat portion 141b and the low flat portion 141c of the driven cam portion 141 are formed at two positions so as to be rotationally symmetrical at intervals of 180 degrees upward. The high flat portion 141b and the low flat portion 141c are formed with a locking recess 141d that engages with the engaging protrusion 112c of the rotating member 11. The abutting portion 142 is a portion protruding downward from the lower left end of the pressing cylinder portion 140, and abuts against the upper surface of the pressing piece 122 of the spring member 12. The extension portion 143 is a portion formed on the right end side of the pressing cylinder portion 140 and extending downward, and is formed into a substantially rectangular parallelepiped shape that is elongated in the vertical direction. The extension portion 143 is arranged between the conducting wall 132 of the terminal member 13 and the inner wall of the housing 10, and has the function of stabilizing the upward and downward movement of the pressing member 14 as described later.

[0115] like Fig. 20As shown in the example, a limiting chamber 103 is formed as a part of the housing 10 between the conducting wall 132 of the terminal member 13 and the inner wall of the housing 10. The limiting chamber 103 is formed in a substantially rectangular parallelepiped shape with a hollow interior and an open upper surface. The force-applying member 15 is accommodated inside the limiting chamber 103. The lower portion of the extension portion 143 of the pressing member 14 is inserted from the upper end of the limiting chamber 103, and the lower end of the extension portion 143 inserted into the limiting chamber 103 abuts against the upper end of the force-applying member 15. The force-applying member 15 abuts against the lower end of the extension portion 143 to apply force to the pressing member 14 upward. By inserting the extension portion 143 of the pressing member 14 into the limiting chamber 103, the movement of the extension portion 143 is limited by the limiting chamber 103, so that the up and down movement of the pressing member 14 is stable.

[0116] The operation of the terminal block 1 formed as described above will be described. Figure 21 to Figure 23 1 is a front schematic diagram showing an example of the terminal block 1 according to the present application. Figure 21 to Figure 23 Various components of the frontmost structural unit 1 a are illustrated in a state where the end surface cover 101 on the front surface of the housing 10 is separated from the terminal block 1 and the interior is visible. Fig.21 It shows the state where no wire 2 is inserted. Fig. 22 Indicates the state of the insertion of the wire 2 or the release of the inserted wire 2. Fig.23 The state where the inserted wire 2 is held is shown.

[0117] exist Fig.21 In the illustrated state, the flat portion 112b formed on the driving cam portion 112 of the rotating member 11 and protruding downward is located at a position corresponding to the low flat portion 141c of the pressing member 14. Since the pressing member 14 is urged upward by the urging member 15, the pressing member 14 rises until the low flat portion 141c abuts against the flat portion 112b of the rotating member 11 protruding downward. Fig.21 In the illustrated state, the pressing member 14 is located at the upper end of the vertical movement range, and the front end side of the pressing piece 122 of the spring member 12 is located at the upper holding position. Fig.21 In the illustrated state, when the wire 2 is not inserted, the front end of the pressing piece 122 of the spring member 12 abuts against the conducting wall 132 or is located near the conducting wall 132, and the upper surface abuts against the pressing member 14 from below. Therefore, the hollow at the center of the rotating member 11 and the hollow at the center of the pressing member 14, which form the insertion passage for the wire 2 to be inserted, are blocked by the pressing piece 122 at their front ends.

[0118] Fig. 22 Indicates the operator’s Fig.21The illustrated state is a state in which the operating portion 111 of the rotating member 11 is operated and the rotating member 11 is rotated clockwise about 30 degrees around the central axis of the rotating cylinder 110. Fig. 22 In the illustrated state, the flat portion 112b formed on the driving cam portion 112 of the rotating member 11 and protruding downward is in contact with the high-position flat portion 141b of the pressing member 14. Fig. 22 In the illustrated state, the pressing member 14 is located at the lower end of the vertical movement range. The pressing member 14 contacts the spring member 12 at the front end of the contact portion 142. The pressing piece 122 of the spring member 12 is pressed downward by the front end of the contact portion 142, so it is bent downward with the bending portion 120 as a fulcrum and is located at the lower release position. Fig. 22 In the illustrated state, when the wire 2 is inserted, the wire 2 is released from the pressing of the pressing piece 122 of the spring member 12, so the wire 2 is easily pulled out. Fig. 22 In the illustrated state, when the wire 2 is not inserted, the wire 2 can be easily inserted because the insertion path through which the wire 2 is inserted is open.

[0119] Fig.23 Indicates the operator’s Fig. 22 The illustrated state is a state where the wire 2 is inserted into the terminal block 1, the operating portion 111 of the rotating member 11 is operated, and the rotating member 11 is rotated counterclockwise about 30 degrees around the central axis of the rotating cylinder 110. Fig.23 In the illustrated state, the pressing piece 122 of the spring member 12 is located at the holding position, pressing the inserted wire 2 toward the conducting wall 132 side of the terminal member 13. By clamping the wire 2 between the pressing piece 122 of the spring member 12 and the conducting wall 132 of the terminal member 13, the wire 2 is held in contact with the conducting wall 132 in the housing 10, and is in a state where it can be conducted with the terminal portion 130.

[0120] Fig.24 This is a perspective view showing an enlarged portion of the terminal block 1 described in the present application. Fig.24 In the figure, the process of the rotating member 11 rotating under the operation of the operator is enlarged and shown with the rotating member 11 and the pressing member 14 as the center. The high flat portion 141b and the low flat portion 141c of the pressing member 14 are formed with a locking recess 141d. Fig.24 When the pressing member 14 is turned right in the illustrated state and raised, the engaging protrusion 112c formed on the flat portion 112b of the downwardly protruding portion of the rotating member 11 is locked in the state of being embedded in the locking recess 141d of the low-position flat portion 141c of the pressing member 14 urged upward by the urging member 15, forming Fig.21 and Fig.23 The state of the instantiation. Fig.21 and Fig.23 In the illustrated state, the engaging protrusion 112c of the rotating member 11 is locked in the state of being embedded in the locking recess 141d of the low flat portion 141c of the pressing member 14 that is forced upward, thereby preventing the rotating member 11 from deviating from the position due to rotation, and stabilizing operations such as one-handed operation. In addition, the operator can sense the impact when the engaging protrusion 112c is locked in the locking recess 141d as a click touch, and can confirm that the operation has been performed to the correct position.

[0121] When the rotating member 11 Fig.24 When the pressing member 14 is turned left in the illustrated state and descends, the engaging protrusion 112c formed on the flat portion 112b of the upwardly protruding portion of the rotating member 11 is locked in the locking recess 141d of the high-position flat portion 141b of the pressing member 14 urged upward by the urging member 15, forming Fig. 22 The state of the instantiation. Fig. 22 In the illustrated state, the engaging convex portion 112c of the rotating member 11 is engaged with the engaging concave portion 141d of the high-position flat portion 141b of the pressing member 14 which is forced upward, thereby preventing the rotating member 11 from rotating from this position, and stabilizing operations such as single-handed operation. In addition, the operator can perceive the impact when the engaging convex portion 112c is engaged with the engaging concave portion 141d as a click touch, and can confirm that the operation has been performed to the correct position. It should be noted that it is appropriate to design a convex portion to be formed on any of the rotating member 11 and the pressing member 14, or to form a concave portion on any of the members, and as long as it is an engageable shape, it can be a shape other than the engaging convex portion 112c and the engaging concave portion 141d.

[0122] As described above, the terminal block 1 of the second embodiment can be easily operated with one hand. In addition, the terminal block 1 of the second embodiment presses the spring member 12 via the pressing member 14 through the rotating member 11, and the pressing member 14, which is restricted in the up and down movement, abuts against the spring member 12, so that the spring member 12 can be prevented from twisting, deviating from the abutting position, and other unstable states. In addition, because the up and down movement of the pressing member 14 of the terminal block 1 is restricted by the limiting chamber 103, the movement is stable. In addition, the terminal block 1 can stabilize the operation for the operator and confirm the accuracy of the operation by locking the engaging protrusion 112c in the locking recess 141d.

[0123] <Third Embodiment>

[0124] The third embodiment is based on the second embodiment, but changes the engagement mechanism between the rotating member 11 and the pressing member 14. In the third embodiment, the same reference numerals as those in the first or second embodiment are used for the same structures as those in the first and second embodiments, and detailed descriptions are omitted.

[0125] Fig.25 It is a three-dimensional overview diagram showing an example of the appearance of the terminal block 1 described in the present application. On the side of the housing 10 of the terminal block 1 of the third embodiment, a locking portion 104 is formed on each structural unit 1a to prevent the rotating part 11 from freely rotating and deviating. The specific function of the locking portion 104 will be described later. It should be noted that the terminal block 1 of the third embodiment illustrates a method of forming the rotating part 11 into a shape in which the rotating part 11 is in a holding position when turned right and in a release position when turned left. In the terminal block 1 of the third embodiment, since the outer shape other than the locking portion 104 and the structure connecting multiple structural units 1a are the same as those of the first embodiment, the first embodiment is referred to.

[0126] Fig.26 This is a front schematic diagram showing an example of the internal structure of the terminal block 1 according to the present application. Fig. 27 This is a schematic perspective view showing an example of various components housed in the housing 10 of the terminal block 1 described in the present application. Fig.26 This is a front schematic diagram showing various components of the frontmost structural unit 1 a in a state where the end surface cover 101 on the front surface side of the housing 10 is separated from the terminal block 1 so that the interior can be clearly seen. Fig. 27 The terminal block 1 is shown as a three-dimensional schematic diagram in which the rotating member 11, the spring member 12, the terminal member 13 and the pressing member 14 stored in the housing 10 are removed so that their relationship can be clearly seen. Fig.26 In the figure, a part of the structure is shown in perspective so that its internal relationship can be seen clearly. In the terminal block 1 of the third embodiment, the force-applying member 15 does not necessarily need to be configured. The lower part of the rotating cylindrical portion 110 of the rotating member 11 is embedded in the pressing cylindrical portion 140 of the pressing member 14 from above. The outer peripheral surface of the rotating cylindrical portion 110 of the rotating member 11 and the inner peripheral surface of the pressing cylindrical portion 140 of the pressing member 14 are engaged by a cam mechanism, and the rotational movement of the rotating member 11, which will become a driving node, is transmitted to the pressing member 14, which will become a driven node, as an up and down movement.

[0127] Fig.28 It is a schematic perspective view showing an example of the rotating member 11 included in the terminal block 1 according to the present application. Fig.28 It is shown from a perspective obliquely below. Figure 26 to Figure 28, the rotating member 11 is described. The rotating member 11 includes a rotating cylindrical portion 110, an operating portion 111, a driving cam portion 112, and other parts. In the rotating member 11 of the terminal block 1 of the third embodiment, the driving cam portion 112 is formed as a spiral circumferential cam protruding from the outer circumferential surface of the rotating cylindrical portion 110. Four spiral circumferential cams are formed at equal intervals on the outer circumferential surface of the rotating cylindrical portion 110. A locking protrusion 111a that engages with the locking portion 104 of the housing 10 is protruding from the lower surface of the operating portion 111.

[0128] Fig.29 It is a schematic perspective view showing an example of the pressing member 14 included in the terminal block 1 according to the present application. Fig.29 It is shown from an oblique upward perspective. Fig.26 and Fig. 27 as well as Fig.29 , the pressing member 14 is described. The pressing member 14 includes a pressing cylinder 140, a driven cam 141, a contact portion 142, an extension portion 143 and the like. In the pressing member 14 of the terminal block 1 of the third embodiment, the driven cam 141 is formed as a spiral circumferential cam recessed in the inner circumferential surface of the pressing cylinder 140. Four spiral circumferential cams are formed at equal intervals on the inner circumferential surface of the pressing cylinder 140. The driven cam 141 is engaged with the driving cam 112 of the rotating member 11, and serves as a driven node relative to the driving cam 112 of the rotating member 11 serving as a driving node, and a cam mechanism is formed by the driving cam 112 and the driven cam 141. The upper end side of the driven cam 141 is open, and the lower end side is sealed by the edge of the inner side of the lower end of the pressing cylinder 140.

[0129] The shapes and functions of other components are substantially the same as those of the second embodiment.

[0130] The operation of the terminal block 1 formed as described above will be described. Figure 30 to Figure 32 1 is a front schematic diagram showing an example of the terminal block 1 according to the present application. Figure 30 to Figure 32 Various components of the frontmost structural unit 1a are illustrated in a state where the end surface cover 101 of the front surface of the housing 10 is separated from the terminal block 1 so that the interior can be seen. In addition, some structures are shown in perspective so that the internal relationship can be seen. Fig.30 Indicates the state where no wire 2 is inserted. Fig.31 Indicates the state of the insertion of the wire 2 or the release of the inserted wire 2. Fig.32 Indicates a state where the inserted wire 2 is retained.

[0131] exist Fig.30In the illustrated state, the pressing member 14 is located at the upper end of the vertical movement range, and the front end side of the pressing piece 122 of the spring member 12 is located at the upper holding position. Fig.30 In the illustrated state, when the wire 2 is not inserted, the front end of the pressing piece 122 of the spring member 12 abuts against the conducting wall 132 or is located near the conducting wall 132, and the upper surface abuts against the pressing member 14 from below. Therefore, the hollow at the center of the rotating member 11 and the hollow at the center of the pressing member 14, which form the insertion passage for the wire 2 to be inserted, are blocked by the pressing piece 122 at their front ends.

[0132] Fig.31 Indicates that the operator Fig.30 The illustrated state is a state in which the operating portion 111 of the rotating member 11 is operated and the rotating member 11 is rotated counterclockwise about 30 degrees around the central axis of the rotating cylindrical portion 110. By rotating the rotating member 11, the pressing member 14 that engages with the driven cam portion 141 and the driving cam portion 112 formed on the outer peripheral surface of the rotating member 11 is actuated. Since the extension portion 143 is inserted into the limiting chamber 103 of the housing 10, the movement direction of the pressing member 14 is restricted in the upper and lower directions. Therefore, by rotating the rotating member 11, the pressing member 14 moves downward. Fig.31 In the illustrated state, the pressing member 14 is located at the lower end of the vertical movement range. The pressing member 14 abuts against the spring member 12 at the front end of the abutment portion 142. The pressing piece 122 of the spring member 12 is pressed downward by the front end of the abutment portion 142, so it is bent downward with the bending portion 120 as a fulcrum and is located at the lower release position. Fig.31 In the illustrated state, when the wire 2 is inserted, the wire 2 is released by the pressing of the pressing piece 122 of the spring member 12, so the wire 2 is easily pulled out. Fig.31 In the illustrated state, when the wire 2 is not inserted, the wire 2 can be easily inserted because the insertion path through which the wire 2 is inserted is open.

[0133] Fig.32 Indicates that the operator Fig.31 The illustrated state is a state where the wire 2 is inserted into the terminal block 1, the operating portion 111 of the rotating member 11 is operated, and the rotating member 11 is rotated clockwise about 30 degrees around the central axis of the rotating cylinder 110. Fig.32 In the illustrated state, the pressing piece 122 of the spring member 12 is located at the holding position, pressing the inserted wire 2 toward the conductive wall 132 side of the terminal member 13. By clamping the wire 2 between the pressing piece 122 of the spring member 12 and the conductive wall 132 of the terminal member 13, the wire 2 is held in contact with the conductive wall 132 in the housing 10, and is in a state where it can be conductive with the terminal portion 130.

[0134] Fig.33 and Fig.34 This is a schematic side view showing an enlarged side surface of a housing 10 of a terminal block 1 according to the present application. Fig.33 Indicates that the inserted wire 2 can be maintained, corresponding to Fig.30 and Fig.32 . Fig.34 Indicates the state of being released from the hold state, corresponding to Fig.31 The locking portion 104 on the side of the housing 10 is formed as an arm-shaped flexible piece extending in a substantially horizontal direction, and is bent downward when pressed from above. A moving passage 104a is engraved on the upper surface of the locking portion 104, and is moved by the locking protrusion 111a of the rotating member 11. The moving passage 104a is formed with concave and convex portions so that the height of the root portion of the arm is low and increases toward the front end at a gentle inclination, and decreases at a steep inclination near the front end.

[0135] Fig.33 In order to hold the wire 2, the operating portion 111 of the rotating member 11 is shown to be at the right-hand limit position within the rotation range. Fig.33 In the illustrated state, the locking protrusion 111 a protrudingly provided on the lower surface of the operating portion 111 of the rotating member 11 is located in a recessed portion near the base of the arm-shaped locking portion 104 . Fig.33 The state that can keep the wire material 2 inserted, when trying to turn the rotating member 11 to the left, the locking projection 111a needs to exceed the inclined force of the moving passage 104a. Therefore, for example, when the wire material 2 is kept, the wire material 2 can be prevented from falling off.

[0136] Fig.34 Indicates that the operator Fig.30 The illustrated state is a state in which the operating portion 111 of the rotating component 11 is operated and turned counterclockwise about 30 degrees around the central axis of the rotating cylindrical portion 110. In order to make the locking protrusion 111a abut against and move the inclined surface of the moving passage 104a of the locking portion 104, the operator applies a force to the rotating operation. Relative to the operator's operation, the locking portion 104 is pressed from above by the locking protrusion 111a, so it bends downward. As the locking portion 104 bends downward, the locking protrusion 111a can move in the moving passage 104a, and the rotating component 11 turns counterclockwise. As the rotating component 11 turns counterclockwise, the pressing piece 122 of the spring component 12 is pressed toward the release position side. Fig.34 In the state shown, the locking protrusion 111a is locked by being inserted into the recess near the front end of the locking portion 104. Fig.34When the rotating member 11 is turned right in the state shown, a strong force needs to be applied to the operating portion 111 because the locking protrusion 111a has to exceed the steep inclination of the moving path 104a. Fig.34 In the illustrated state, since the rotating member 11 is configured to be difficult to turn right even when pressed upward by the spring member 12 , the operator can perform the operation with his hands off the operating portion 111 .

[0137] As described above, the terminal block 1 of the third embodiment has a spiral circumferential cam as a driving cam portion 112 formed on the outer circumferential surface of the rotating cylindrical portion 110 of the rotating member 11, and a spiral circumferential cam as a driven cam portion 141 formed on the inner circumferential surface of the pressing cylindrical portion 140 of the pressing member 14. The terminal block 1 moves the pressing member 14 in the up-down direction by the rotating action of the rotating member 11. The rotating member 11 presses the spring member 12 via the pressing member 14, and the pressing member 14, whose movement is restricted during the up-down movement, abuts against the spring member 12, so that the spring member 12 can be prevented from being twisted, deviating from the abutting position, or other unstable conditions. In addition, since the driving cam portion 112 and the driven cam portion 141 of the terminal block 1 are engaged as circumferential cams, the force applying member 15 can be omitted. In addition, the terminal block 1 is engaged with the locking protrusion 111a formed on the rotating member 11 to limit the rotation of the rotating member 11, so the rotating member 11 can be fixed in the holding position to prevent the retained wire 2 from falling off. In addition, by fixing it in the release position, it can be easily operated by one hand by the operator.

[0138] <Fourth embodiment>

[0139] The fourth embodiment is based on the third embodiment, and the engagement mechanism of the rotating member 11 and the pressing member 14 is changed. In the fourth embodiment, for the same structure as any one of the first to third embodiments, the same reference numerals as the first to third embodiments are used, and detailed description is omitted. The outer shape of the terminal block 1 and the structure connecting the plurality of structural units 1a of the fourth embodiment are substantially the same as those of the first embodiment, so the first embodiment is referred to.

[0140] Fig.35 This is a front schematic diagram showing an example of the internal structure of the terminal block 1 according to the present application. Fig.36 This is a schematic perspective view showing an example of various components housed in the housing 10 of the terminal block 1 described in the present application. Fig.35 This is a front schematic diagram showing various components of the frontmost structural unit 1 a in a state where the end surface cover 101 on the front surface side of the housing 10 is separated from the terminal block 1 so that the interior can be clearly seen. Fig.36The terminal block 1 is shown as a three-dimensional schematic diagram in which the rotating member 11, the spring member 12, the terminal member 13 and the pressing member 14 stored in the housing 10 are removed so that their relationship can be clearly seen. Fig.35 and Fig.36 In the figure, a part of the structure is shown in perspective so that the internal relationship can be seen clearly. In the terminal block 1 of the fourth embodiment, it is not necessary to configure the force-applying member 15. The lower part of the rotating cylindrical portion 110 of the rotating member 11 is embedded in the pressing cylindrical portion 140 of the pressing member 14. The outer peripheral surface of the rotating cylindrical portion 110 of the rotating member 11 and the inner peripheral surface of the pressing cylindrical portion 140 of the pressing member 14 are engaged by a cam mechanism, and the rotational movement of the rotating member 11, which will become the driving node, is transmitted to the pressing member 14, which will become the driven node, as an up and down movement.

[0141] Fig.37 It is a schematic perspective view showing an example of the rotating member 11 included in the terminal block 1 according to the present application. Fig.37 It is shown from a perspective obliquely below. Figure 35 to Figure 37 , the rotating member 11 is described. The rotating member 11 includes a rotating cylindrical portion 110, an operating portion 111, a driving cam portion 112, and the like. In the rotating member 11 of the terminal block 1 of the fourth embodiment, the driving cam portion 112 is formed as a roughly cylindrical protrusion protruding from the outer peripheral surface of the rotating cylindrical portion 110. The roughly cylindrical protrusion is formed at four locations on the outer peripheral surface of the rotating cylindrical surface at intervals of about 90 degrees.

[0142] Fig.38 and Fig.39 It is a schematic perspective view showing an example of the pressing member 14 included in the terminal block 1 according to the present application. Fig.38 and Fig.39 The images are shown from different angles above. Fig.35 and Fig.36 ,as well as Fig.38 and Fig.39, the pressing member 14 is described. The pressing member 14 includes a pressing cylinder 140, a driven cam 141, a contact portion 142, an extension portion 143 and the like. In the pressing member 14 of the terminal block 1 of the fourth embodiment, the driven cam 141 is a circumferential cam formed on the inner circumference of the pressing cylinder 140, and specifically, is recessed as a spiral groove on the inner circumference. Four spiral circumferential cams are formed at equal intervals on the inner circumference of the pressing cylinder 140. The driven cam 141 is engaged with the driving cam 112 of the rotating member 11, and serves as a driven node relative to the driving cam 112 of the rotating member 11 serving as a driving node, and a cam mechanism is formed by the driving cam 112 and the driven cam 141. The driven cam 141 has a high-position flat portion 141b extending in a substantially horizontal direction (circumferential direction) formed at the upper end of the spiral driven inclined portion 141a. The front end of the high flat portion 141b of the driven cam portion 141 is formed with a downward recess as an engaging recess 141e. The lower end side of the driven cam portion 141 is open. The driven inclined portion 141a of the driven cam portion 141 is a groove recessed in the inner circumferential surface, and the high flat portion 141b passes through from the inner circumferential surface to the outer circumferential surface. With respect to a virtual plane orthogonal to the axial direction of the pressing cylindrical portion 140 of the pressing component 14, the driven inclined portion 141a is obliquely formed, and the high flat portion 141b and the low flat portion 141c are formed roughly in parallel. The roughly cylindrical protrusion formed as the driving cam portion 112 on the rotating component 11 is engaged with the groove recessed in the inner circumferential surface of the pressing component 14 as the driven cam portion 141, and moves along the driven inclined portion 141a and the high flat portion 141b.

[0143] The shapes and functions of other components are substantially the same as those of the third embodiment.

[0144] The operation of the terminal block 1 formed as described above will be described. Figure 40 to Figure 42 1 is a front schematic diagram showing an example of the terminal block 1 according to the present application. Figure 40 to Figure 42 Various components of the frontmost structural unit 1a are illustrated in a state where the front cover of the housing 10 is separated from the terminal block 1 and the interior is visible. In addition, some structures are shown transparently so that the internal relationship can be seen. Fig.40 Indicates the state where no wire 2 is inserted. Fig.41 Indicates the state of the insertion of the wire 2 or the release of the inserted wire 2. Fig.42 The state where the inserted wire 2 is held is shown.

[0145] exist Fig.40 In the illustrated state, the pressing member 14 is located at the upper end of the vertical movement range, and the front end side of the pressing piece 122 of the spring member 12 is located at the upper holding position. Fig.40In the illustrated state, when the wire 2 is not inserted, the front end of the pressing piece 122 of the spring member 12 abuts against the conducting wall 132 or is located near the conducting wall 132, and the upper surface abuts against the pressing member 14 from below. Therefore, the hollow at the center of the rotating member 11 and the hollow at the center of the pressing member 14, which form the insertion passage for the wire 2 to be inserted, are blocked by the pressing piece 122 at their front ends.

[0146] Fig.41 Indicates that the operator Fig.40 The illustrated state is a state in which the operating portion 111 of the rotating member 11 is operated and the rotating member 11 is rotated counterclockwise by about 30 degrees around the central axis of the rotating cylinder portion 110. By rotating the rotating member 11, the pressing member 14 having a driven cam portion 141 engaged with the driving cam portion 112 is actuated by the action of a roughly cylindrical protrusion formed on the rotating member 11 as a driving cam portion 112. Because the extension portion 143 is inserted into the limiting chamber 103 of the housing 10, the movement direction of the pressing member 14 is restricted vertically. Therefore, by turning the rotating member 11 counterclockwise, the pressing member 14 moves downward. Fig.41 In the illustrated state, the pressing member 14 is located at the lower end of the vertical movement range. The pressing member 14 contacts the spring member 12 at the front end of the contact portion 142. The pressing piece 122 of the spring member 12 is pressed downward by the front end of the contact portion 142, so it is bent downward with the bending portion 120 as a fulcrum and is located at the lower release position. Fig.41 In the illustrated state, when the wire 2 is inserted, the wire 2 is released from the pressing of the pressing piece 122 of the spring member 12, so the wire 2 is easily pulled out. Fig.41 In the illustrated state, when the wire 2 is not inserted, the wire 2 can be easily inserted because the insertion path through which the wire 2 is inserted is open.

[0147] exist Fig.41In the illustrated state, the roughly cylindrical protrusion formed as the driving cam portion 112 of the rotating member 11 is located at the front end of the high flat portion 141b formed as the driven cam portion 141 of the pressing member 14, that is, the engaging recessed portion 141e. By the rotation of the rotating member 11, the protrusion of the driving cam portion 112 moves along the spiral driven inclined portion 141a of the driven cam portion 141 and moves to the high flat portion 141b. The protrusion of the driving cam portion 112 is located at the high flat portion 141b, thereby preventing the rotating member 11 from turning right even if it is pressed upward from the spring member 12. In addition, when the protrusion of the driving cam portion 112 is moved to the front end of the high flat portion 141b, that is, the engaging recessed portion 141e, the driving cam portion 112 engages with the engaging recessed portion 141e. The engagement of the projection with the engagement recess 141e makes it difficult for the rotating member 11 to turn right, so the operator can work with his hands off the operating portion 111. In addition, the operator recognizes the impact generated when the projection engages with the engagement recess 141e as a click feeling.

[0148] Fig.42 Indicates the operator’s Fig.41 The illustrated state is a state in which the wire 2 is inserted into the terminal block 1, the operating portion 111 of the rotating member 11 is operated, and the rotating member 11 is rotated clockwise about 30 degrees around the central axis of the rotating cylinder 110. Fig.42 In the illustrated state, the pressing piece 122 of the spring member 12 is located at the holding position, pressing the inserted wire 2 toward the conductive wall 132 side of the terminal member 13. By clamping the wire 2 between the pressing piece 122 of the spring member 12 and the conductive wall 132 of the terminal member 13, the wire 2 is held in contact with the conductive wall 132 in the housing 10, and is in a state where it can be conductive with the terminal portion 130.

[0149] As described above, the terminal block 1 of the fourth embodiment has a substantially cylindrical protrusion as the driving cam portion 112 provided on the rotating member 11, and a spiral groove portion is recessed as the driven cam portion 141 on the inner circumferential surface of the pressing member 14. The terminal block 1 moves the pressing member 14 in the vertical direction by the rotating action of the rotating member 11. The rotating member 11 presses the spring member 12 via the pressing member 14, thereby the pressing member 14 whose movement is restricted in the vertical movement abuts against the spring member 12, so that the spring member 12 can be prevented from being twisted, deviating from the abutting position, and other unstable states. In addition, since the driving cam portion 112 and the driven cam portion 141 of the terminal block 1 are engaged as circumferential cams, the force applying member 15 can be omitted. In addition, the terminal block 1 can restrict the rotating action of the rotating member 11 by forming the high-position flat portion 141b and the engaging recessed portion 141e in the groove portion formed as the driven cam portion 141 of the pressing member 14, so that the operator can easily perform one-handed operation. Furthermore, since the lower end side of the driven cam portion 141 of the pressing member 14 of the terminal block 1 is open, when the component is formed by a molding method such as injection molding, when the resin solidified into the shape of the component is taken out from the mold, the mold can be relatively rotated and led downward to be taken out. Therefore, the molding process can be simplified.

[0150] <Fifth Embodiment>

[0151] The fifth embodiment is based on the fourth embodiment, and is a method of cooperating the spring member 12 and the pressing member 14 that are supported in a swingable manner. In the fifth embodiment, for the same structure as any of the first to fourth embodiments, the same reference numerals as the first to fourth embodiments are used, and detailed descriptions are omitted. The outer shape of the terminal block 1 and the structure of connecting a plurality of structural units 1a in the fifth embodiment are substantially the same as those in the first embodiment, so the first embodiment is referred to.

[0152] Fig.43 This is a front schematic diagram showing an example of the internal structure of the terminal block 1 according to the present application. Fig.44 and Fig.45 This is a schematic perspective view showing an example of various components housed in the housing 10 of the terminal block 1 described in the present application. Fig.43 This is a front schematic diagram showing various components of the frontmost structural unit 1 a in a state where the end surface cover 101 on the front surface side of the housing 10 is separated from the terminal block 1 so that the interior can be clearly seen. Fig.44 The terminal block 1 is shown as a schematic three-dimensional view in which the rotating member 11 , the spring member 12 , the terminal member 13 , and the pressing member 14 housed in the housing 10 are removed so that the relationship between them can be clearly seen. Fig.45 Expressed as from Fig.44The illustrated stereoscopic overview diagram is a stereoscopic overview diagram in which the rotating component 11 is further removed so that the relationship between other components can be clearly seen. In the terminal block 1 of the fifth embodiment, it is not necessary to configure the force-applying component 15. The lower part of the rotating cylindrical portion 110 of the rotating component 11 is embedded from the upper part of the pressing cylindrical portion 140 of the pressing component 14. The outer peripheral surface of the rotating cylindrical portion 110 of the rotating component 11 and the inner peripheral surface of the pressing component 14 are engaged by a cam mechanism, and the rotational movement of the rotating component 11, which will become a driving node, is transmitted as the up and down movement of the pressing component 14, which will become a driven node.

[0153] Fig.46 It is a schematic perspective view showing an example of the rotating member 11 included in the terminal block 1 according to the present application. Fig.46 It is shown from a perspective obliquely below. Figure 43 to Figure 46 , the rotating member 11 is described. The rotating member 11 includes a rotating cylindrical portion 110, an operating portion 111, a driving cam portion 112, and the like. In the rotating member 11 of the terminal block 1 of the fifth embodiment, the driving cam portion 112 is formed as a roughly cylindrical protrusion protruding from the outer peripheral surface of the rotating cylindrical portion 110. The roughly cylindrical protrusion is formed at four locations on the outer peripheral surface of the rotating cylindrical surface at intervals of approximately 90 degrees.

[0154] Fig.47 1 is a perspective view schematically showing an example of the spring member 12 included in the terminal block 1 according to the present application. Figure 43 to Figure 45 as well as Fig.47 , the spring member 12 will be described. The spring member 12 of the terminal block 1 is formed in a shape of a flexible material such as a metal thin plate bent at two locations. The spring member 12 of the terminal block 1 of the fifth embodiment is supported by the terminal member 13 via a rod-shaped shaft member 16 so as to be swingable. One of the two locations of the bent portion of the spring member 12 is a supported portion 124 supported by the shaft member 16 so as to be swingable. In the spring member 12, a piece extending from the supported portion 124 through the other bent portion is a support piece 125 supported by the pressing member 14, and the other piece extending from the supported portion 124 is a pressing piece 122 used as a leaf spring for pressing the inserted wire 2. The front end of the support piece 125 of the spring member 12 is supported in a state of abutting against the upper surface of the abutment portion 142 extending from the lower end of the pressing member 14.

[0155] Fig.48 and Fig.49 It is a schematic perspective view showing an example of the pressing member 14 included in the terminal block 1 according to the present application. Fig.48 It is shown from an oblique upward perspective. Fig.49 It is shown from a perspective obliquely below. Figure 43 to Figure 45 ,as well as Fig.48 and Fig.49 Next, the pressing member 14 will be described. The pressing member 14 includes a pressing cylindrical portion 140, a driven cam portion 141, a contact portion 142, an extending portion 143, and the like.

[0156] In the pressing member 14 of the terminal block 1 of the fifth embodiment, the driven cam portion 141 is a circumferential cam formed on the inner circumferential surface of the pressing cylindrical portion 140, and is recessed as a spiral groove portion. Four spiral circumferential cams, i.e., the driven cam portions 141, are formed at equal intervals on the inner circumferential surface of the pressing cylindrical portion 140. The driven cam portion 141 is engaged with the driving cam portion 112 of the rotating member 11, and serves as a driven node relative to the driving cam portion 112 of the rotating driving member serving as a driving node, and a cam mechanism is formed by the driving cam portion 112 and the driven cam portion 141. The driven cam portion 141 has a low flat portion 141c extending in a substantially horizontal direction formed at the lower end of the spiral driven inclined portion 141a. The driven inclined portion 141a of the driven cam portion 141 is a groove recessed in the inner circumferential surface. The lower end side of the low flat portion 141c formed at the lower end of the driven cam portion 141 is open. The driven inclined portion 141a is formed obliquely and the low flat portion 141c is formed approximately parallel to a virtual plane orthogonal to the axial direction of the pressing cylindrical portion 140 of the pressing member 14. The approximately cylindrical protrusion formed as the driving cam portion 112 on the rotating member 11 is engaged with the groove portion recessed as the driven cam portion 141 on the inner circumferential surface of the pressing member 14, and moves along the driven inclined portion 141a and the low flat portion 141c.

[0157] In the pressing member 14 of the terminal block 1 of the fifth embodiment, the contact portion 142 is a portion protruding to the left from the lower left end of the pressing cylindrical portion 140. The contact portion 142 is formed in a shape in which a part of the circumference of the lower end of the cylinder protrudes outward, and the protruding front end side is formed in an arc shape that is substantially parallel to the circumference, and the upper surface and the lower surface are horizontal planes that are substantially parallel to each other. The upper surface of the contact portion 142 of the pressing member 14 contacts the support piece 125 of the spring member 12.

[0158] The terminal member 13 has a terminal portion 130 and a conducting wall 132 that serve as a busbar, a fixed wall 131, and a connecting wall 133. The fixed wall 131 is provided with a shaft support portion 131a through which the shaft member 16 is inserted and which supports the spring member 12 in a swingable manner. The shaft member 16 inserted through the shaft support portion 131a supports the spring member 12 via the shaft supported portion 124.

[0159] When the pressing member 14 rises, the support piece 125 of the spring member 12 is pressed upward from the abutment portion 142 of the pressing member 14, and the spring member 12 swings in the direction in which the support piece 125 rises (facing the support piece 125). Fig.45 When the pressing member 14 is lowered, the spring member 12 is moved in the direction of the pressing member 122 lowering (facing the direction of the pressing member 122) due to the deadweight of the pressing member 122. Fig.45 The support piece 125 is lowered together with the contact portion 142 while being in contact with the contact portion 142 of the pressing member 14, and the pressing piece 122 moves to the release position side.

[0160] The shapes and functions of other components are substantially the same as those of the fourth embodiment.

[0161] The operation of the terminal block 1 formed as described above will be described. Figure 50 to Figure 52 1 is a front schematic diagram showing an example of the terminal block 1 according to the present application. Figure 50 to Figure 52 Various components of the frontmost structural unit 1 a are illustrated in a state where the front cover of the housing 10 is separated from the terminal block 1 and the interior is visible. Fig.50 It shows the state where no wire 2 is inserted. Fig.51 Indicates the state of the insertion of the wire 2 or the release of the inserted wire 2. Fig.52 The state where the inserted wire 2 is held is shown.

[0162] exist Fig.50 In the illustrated state, the pressing member 14 is located at the upper end of the vertical movement range, and the front end side of the pressing piece 122 of the spring member 12 is located at the upper holding position. Fig.50 In the illustrated state, when the wire 2 is not inserted, the front end of the pressing piece 122 of the spring member 12 abuts against the conducting wall 132 or is located near the conducting wall 132, and the upper surface abuts against the pressing member 14 from below. Therefore, the hollow at the center of the rotating member 11 and the hollow at the center of the pressing member 14, which form the insertion passage for the wire 2 to be inserted, are blocked by the pressing piece 122 at their front ends.

[0163] Fig.51 Indicates the operator’s Fig.50The illustrated state is a state in which the operating portion 111 of the rotating member 11 is operated and the rotating member 11 is rotated clockwise by about 30 degrees around the central axis of the rotating cylinder portion 110. By rotating the rotating member 11, the pressing member 14 having a driven cam portion 141 engaged with the driving cam portion 112 is actuated by the action of a roughly cylindrical protrusion formed on the rotating member 11 as a driving cam portion 112. Because the extension portion 143 is inserted into the limiting chamber 103 of the housing 10, the movement direction of the pressing member 14 is restricted vertically. Therefore, by turning the rotating member 11 clockwise, the pressing member 14 moves downward. Fig.51 In the illustrated state, the pressing member 14 is located at the lower end of the vertical moving range. The pressing member 14 abuts against the spring member 12 at the upper surface of the abutment portion 142, supporting the spring member 12 from below. As the pressing member 14 descends, the supporting piece 125 supported in the state of abutting against the abutment portion 142 of the pressing member 14 loses support from below, so the spring member 12 swings around the axially supported portion 124 as the swing center due to the deadweight of the pressing piece 122 side. Due to the swinging of the spring member 12, the pressing piece 122 becomes in the state of being located at the lower release position. Fig.51 In the illustrated state, when the wire 2 is inserted, the wire 2 is released from the pressing of the pressing piece 122 of the spring member 12, so the wire 2 is easily pulled out. Fig.51 In the illustrated state, when the wire 2 is not inserted, the wire 2 can be easily inserted because the insertion path through which the wire 2 is inserted is open.

[0164] Fig.52 Indicates the operator’s Fig.51 The illustrated state is a state where the wire 2 is inserted into the terminal block 1, the operating portion 111 of the rotating member 11 is operated, and the rotating member 11 is rotated counterclockwise about 30 degrees around the central axis of the rotating cylinder 110. By rotating the rotating member 11 counterclockwise, the pressing member 14 moves upward. Fig.52 In the illustrated state, the pressing member 14 is located at the upper end of the vertical movement range. The support piece 125 of the spring member 12 is pressed upward by the upper surface of the abutment portion 142 of the pressing member 14, so that the spring member 12 swings around the shaft support portion 124 as the swing center, and the pressing piece 122 is in a state of being located at the holding position side. Fig.52 In the illustrated state, the pressing piece 122 of the spring member 12 is located at the holding position, pressing the inserted wire 2 toward the conductive wall 132 side of the terminal member 13. By clamping the wire 2 between the pressing piece 122 of the spring member 12 and the conductive wall 132 of the terminal member 13, the wire 2 is held in contact with the conductive wall 132 in the housing 10, and is in a state where it can be conductive with the terminal portion 130.

[0165] exist Fig.52 In the illustrated state, the roughly cylindrical protrusion formed as the driving cam portion 112 of the rotating member 11 is located at the low flat portion 141c formed as the driven cam portion 141 of the pressing member 14. By the rotation of the rotating member 11, the protrusion of the driving cam portion 112 moves along the spiral driven inclined portion 141a of the driven cam portion 141 and moves to the low flat portion 141c. By the protrusion of the driving cam portion 112 being located at the low flat portion 141c, for example, when the wire 2 is held, the wire 2 is prevented from falling off.

[0166] Fig.53 It is a schematic perspective view showing an example of the pressing member 14 included in the terminal block 1 according to the present application. Fig.53 It is shown from a perspective diagonally below. Fig.53 A mode in which a part of the pressing member 14 included in the terminal block 1 of the fifth embodiment is deformed is shown. Fig.53 The illustrated pressing member 14 has an upwardly recessed engaging recess 141e formed at the front end of the low flat portion 141c. When the rotating member 11 is rotated to the left and the spring member 12 is moved to the holding position, when the protrusion of the driving cam portion 112 is moved to the front end of the low flat portion 141c, i.e., the engaging recess 141e, the driving cam portion 112 engages with the engaging recess 141e. The engaging of the protrusion with the engaging recess 141e makes it difficult for the rotating member 11 to rotate to the left, so the operator can take his hand off the operating portion 111 to perform the operation. In addition, the operator recognizes the impact generated when the protrusion engages with the engaging recess 141e as a click touch.

[0167] As described above, in the terminal block 1 of the fifth embodiment, the pressing member 14 that moves up and down relative to the rotation of the rotating member 11 supports the support piece 125 of the swingable spring member 12, and the spring member 12 is linked to the up and down movement of the pressing member 14 and swings between the release position and the holding position. The spring member 12 is swung by the rotating member 11 via the pressing member 14, and the pressing member 14 whose up and down movement is restricted abuts against the spring member 12, so that the spring member 12 can be prevented from being twisted, deviating from the abutting position, and other unstable states. In addition, since the driving cam portion 112 and the driven cam portion 141 of the terminal block 1 are engaged as a circumferential cam, the force applying member 15 can be omitted. In addition, the terminal block 1 forms a high-position flat portion 141b and an engaging recessed portion 141e in the groove portion formed as the driven cam portion 141 of the pressing member 14, thereby restricting the rotation of the rotating member 11. In addition, since the lower end side of the driven cam portion 141 of the pressing member 14 of the terminal block 1 is open, when the component is formed by a molding method such as injection molding, when the resin solidified into the shape of the component is taken out from the mold, it can be taken out by relatively rotating the mold and leading it downward. Therefore, the molding process can be simplified.

[0171] like Figure 54 to Figure 56As shown, the terminal block device 4 has a terminal block 1 and a connector 3 to which the terminal block 1 can be mounted. The terminal block device 4 is formed into a rectangular box with an open upper surface. In order to embed the terminal block 1, the shape of the inner side of the terminal block device 4 is combined with the outer shape of the housing 10 of the terminal block 1.

[0172] The terminal block 1 used in the terminal block device 4 is formed with an insertion locking portion 101a for locking in a state of being inserted into the connector 3 on the end surface cover 101 which becomes the front surface and the back surface of the housing 10. A terminal protection portion 101b for protecting the terminal portion 130 protruding from the housing 10 is formed at the lower part of the housing 10 of the terminal block 1. A through hole 105 is penetrated from the front side to the back side in the housing 10 of the terminal block 1, and a through component 17 penetrates the through hole 105. The through component 17 is a component that penetrates a plurality of connected structural units 1a and fixes the structural units 1a in a connected state. The through component 17 illustrated in the sixth embodiment is composed of a slender metal pin, and the front end portion is a screw, which is screwed by the end surface cover 101 which becomes the terminal end of the through hole 105. The rear end of the through component 17 is formed in a shape fixed to the entrance portion of the through hole 105. The through-part 17 penetrates through the connected multiple structural units 1a, so that the connected state can be firmly maintained. The through-part 17 prevents the connected multiple structural units 1a from being separated when the terminal block 1 is installed in the connector 3 or removed from the connector 3. As long as the through-part 17 can fix the connected multiple structural units 1a, the shape used for fixing can be appropriately designed, for example, it can be developed into various forms such as a structure in which the rear end side is a screw, a structure in which both ends are fixed by other components, etc.

[0173] When the connector 3 formed in a box shape with an open upper surface is mounted with the terminal block 1, a locking receiving portion 30 is formed on the inner side surface to engage with the embedded locking portion 101a of the terminal block 1 and to lock the terminal block 1. In addition, the connector 3 has a receiving terminal portion 31 that is electrically connected to the terminal portion 130 of the terminal block 1 when the terminal block 1 is mounted on the inner bottom of the box shape. A substrate terminal portion 32 that is mounted on a substrate and is used to be electrically connected to the wiring formed on the substrate is formed on the outer bottom of the connector 3. The receiving terminal portion 31 is electrically connected to the substrate terminal portion 32. When the terminal block 1 is mounted on the connector 3 and the wire 2 is inserted into the terminal block 1, the wire 2 is electrically connected to the substrate terminal portion 32 of the connector 3, and is also electrically connected to the wiring formed on the substrate. Figure 54 to Figure 56 The illustrated terminal block device 4 is a vertical terminal block device 4 in which the direction in which the wires 2 are inserted is substantially perpendicular to the upper surface of the substrate on which the connector 3 is mounted when the terminal block device 4 is mounted on the substrate.

[0174] Fig.57 and Fig.58It is a perspective schematic diagram showing an example of the appearance of the terminal block device 4 according to the present application. Fig.57 This shows the state where the terminal block 1 and the connector 3 are separated. Fig.58 The state in which the terminal block 1 is mounted on the connector 3 is shown. Fig.57 and Fig.58 is to use Figure 54 to Figure 56 Another embodiment of the terminal block device 4 will be described.

[0175] The connector 3 is formed in a box shape with open side surfaces. The terminal block 1 is attached to the open side surfaces of the connector 3 so as to fit the terminal portion 130 below from the side in a flat state. Fig.57 and Fig.58 The illustrated terminal block device 4 is a horizontal type terminal block device 4 in which the direction in which the wires 2 are inserted is substantially parallel to the upper surface of the substrate on which the connector 3 is mounted when the terminal block device 4 is mounted on the substrate.
